Best warm pants

  • Familiarity: I've used it several times
  • Fit: Runs large
  • Size Bought: XS

I bought one pair on Patagonia website and love it so much that I don’t want to wear anything else! So I bought two more pairs and one pair for my husband! They are warm and comfy! I wish they would be a little tighter on the legs.

Cozy and Warm — but too big!

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs large
  • Size Bought: M

I’ve been on the hunt for warmer running tights. These feel pretty warm but I’m sending them back because they’re a bit too big.

Comments on sizing:
I’m typically between M and L, prefer my clothes more fitted, but where I typically run into trouble with Medium sized clothing is if the waistband is too tight. These are super comfortable and if anything the waistband feels a bit loose. It does have an adjustable elastic, just enough to keep them synched. After wearing this around the house for only a few hours, they have stretched out too much to my liking so they’ll be returned. I purchased a M in these but have also tried the Patagonia Pack Out tights, which were too tight and low-waisted in M and too loose and big in a L. These fit more on the roomier size for a M, closer to an L. Much looser than the Peak Mission in the same size, which I also have from Patagonia. I barely fit into those by comparison and they have a tighter waistband.

I just bought a pair in size M for my friend, she is 5’4” and 137lb, do you think I should exchange them for S? Thank you!

Didn’t fit quite right

  • Familiarity: I returned this product before using it
  • Fit: Runs large
  • Size Bought: Xs and small- small too big

I would have loved to keep these warm polartec leggings, however the smalls were too baggy and the xs were too short! They’re exactly what I’m looking for to walk outside daily in NE Ohio when the temps dip into the 20’s, without needing to put another layer on. Anything under 25, and with wind chills lower than 20, you’d def need another layer.

So overused and still excellent.

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: S

Got these in black & green that are over 3yrs old. Using them as base layer for skiing and also as work uniform during fall-winter hahah. I’m 5ft 118lbs in Small. Great not-too-tight fit. They still look and feel like new so I must get the blue one. Excellent buy!

great multi-purpose tight

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: small

I got these to wear as a warm base layer for skiing under my Snowbelle pants because I'm always cold. I'm also wearing them on freezing New England days around the house. I'm 5'5" with an athletic shape and got a small. I purchased navy and already want to order the black,.

Thank you for the review, Michaela!

Glad to hear it has worked out well.

My Wife's Review

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: medium

These are the best leggings ever. I guess they’re not technically leggings, but that’s how I use them. I love the soft fleece lining. I have yet to be cold while wearing them and they are super comfy.

Loved them.... but

  • Fit: True to size
  • Size Bought: xs

There was a slight defect in the sewing in the crotch area that created a poor fit there, so I have to return them. I got a size XS and they fit well otherwise (102 lbs., 5 ft 2 in)

Versatile and comfy

    I got these for my wife and she uses them for everything. Although Patagonia's sizing can be funky these were properly sized.

    Formfitting: Conforms to the body's contours.
    Slim Fit: Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.
    Regular Fit: Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers.
    Relaxed Fit: Drapes loosely on the body.
    How to Measure:
    Measurements refer to body size, not garment dimensions. For best results, take measurements over your underwear.
    Measure under your arms, around the fullest part of your chest.
    Measure around your natural waistline, keeping the tape a bit loose.
    Measure around the fullest part of your body at the top of your legs.
    Inseam will vary depending on style; when lengths are offered, "short" is 30, "regular" is 32 and "long" is 33. Using pants that fit well, measure the crotch seam to the bottom of the leg.
